The Mariazellerbahn model railway reproduces, on H0e scale (1:87), the spectacular landscape of the mountain section from Laubenbachmühle to just after Erlaufklause, with all the stations, tunnels and bridges. Eight trains run on it, which can be operated by the visitor. Documentation includes showpieces, models, old periodicals, and photographs, and describes the history of the Mariazellerbahn.

In the museum shop, you can buy books, periodicals, souvenirs, photos, picture postcards as well as model railways and accessories, with the focus on narrow gauge railways.

The museum is open every Sunday from 1 p.m. to 4 p.m. With advance notice, groups of 10 people and over can be accommodated at other times.
